25 Araneae. 227 
In the synoptic table on p. 151 in Trans. S. Afr. Phil. Soc, Vol. XV, 1904, this species would fall 
under section b G and may be distinguished from the other species in this section by having no median black 
stripe behind the ocular tubercle.

Specimens. 1 d, 2 9? and 7 juv. from Rooibank near Walfishbay, Southern Hereroland, 
May 1905. 
The black markings of the type-specimen in the South African Museum appear to be very fugaceous, 
for at the present time (three years after the original description was made) these markings are only just 
traceable with the assistance of the original description on the cephalothorax, while those on the legs have 
almost entirely disappeared. As the specimen had been in the Collection for more than four years pre- 
viously, it is evident that it must have been considerably bleached already at the time the description was 
made and that the markings must originally have been much stronger and more extensive. In Dr. Schultze's 
specimens the markings are well-preserved and agree exactly in the pattern with those of the typical form, 
excepting that additional ones are present as well, as may have been expected. 
Colour of Dr. Schultze's specimens. Cephalothorax with the median stripe well-developed, 
reaching to highest point of cephalothorax and bordered on each side by an equally narrow yellow stripe, 
which is widened at anterior end behind the median eyes ; on each side of this again, is a narrow black 
stripe, which runs in well-marked specimens from the innerside of the lateral eyes backwards to just be}'ond 
the highest part of the cephalothorax, but usually this line is interrupted posteriorly just before the highest 
part and disconnected anteriorly from the lateral eyes ; outside of this line and at some distance from it is 
a narrow black stripe which, starting from the lateral angles of the clypeus, runs backwards over the lateral 
eyes and some distance beyond, then curving outwards and then inwards again ends somewhere on the 
posterior slope of the thorax; this line and the one just before mentioned enclose between them on each 
side a long broad yellow area, which is divided in well-marked specimens by a transverse black bridge into 
a small anterior and a large posterior yellow area ; sides of the- cephalothorax each with two well-marked 
rows of large yellow areas, defined by a network of black stripes. Femora with well-marked basal, sub- 
mesial and apical black bands below and black spots in between ; patellae blackened at apex ; tibiae with 
3 black bands ; metatarsi blackened at apex. Sternum with some small marginal but no mesial spots. 
Abdomen well-marked with black spots and stripes. 
d (not previously described). Palpal organ much longer than the tarsus, intermediate in shape 
between that of S. flagellata and testudo Purc. (Trans. S. Afr. Phil. Soc, Vol. XV, pl. 10, figs. 15 and 17, 1904), 
the proximal portion of the process slightly thicker distally and pointed, the slender distal portion dark, 
slightly curved, about 2 /s or 3 / i as long as the proximal portion and provided at its base with a small slender 
wing or keel (visible from the side). The palpal organ of S. subulata Purc. is very like that of arenacea 
Purc, except that in subulata the distal part of the process is a trifle longer and its basal keel is less distinct. 
Length ß 3 3 A mm > ?? 3 1 /*— 4'A mm. 
Dr. Schultze also collected 4 young Scytodes from Prince of Wales Bay and Angra Pequena.
